Hello!<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I was working on CFD simulations of a wind tunnel testing. I used Large Eddy Simulation (LES) as the Viscous Model. At the Velocity Inlet, I used a UDF for the X-velocity, which follows the power law. Y- and Z-velocity are zero. For the input regarding turbulence. I selected Spectral Synthesizer for Fluctuating Velocity Algorithm. I used Intensity and Length Scale for the Specification Method. Turbulence Intensity is 10%, and Turbulent Length Scale is 0.01 m.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
After the calculation is completed. I would like to plot the contour of turbulence intensity for the computational domain, but I cannot find turbulence intensity from the drop down list. I only found Subgrid Turbulent Viscosity, subgrid Effective Viscosity, subgrid Turbulent Viscosity Ratio and subgrid Filter length.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I also tried Custom Field Function, but turbulence intensity is calculated based on turbulence kinetic energy and mean velocity. Turbulence kinetic energy is also not available in the outputs.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I am wondering whether you can give me some suggestions on how to plot turbulence intensity contour when LES turbulence model is used.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Another question is that will turbulence intensity decay with the distance from the velocity inlet? If it decays with distance, how can I evaluate the turbulence intensity at the inlet to make sure turbulence intensity of the location of interest will reach the expected value?<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Any help are greatly appreciated.<\/p>\n
<\/p>\n
